Prompt Title: NestJS API Wrapper Structure.

When an application has more than 300 routes, it's essential to organize it into modules to improve maintainability and scalability. Here's a potential structure for a NestJS application with more than 300 routes:

In this structure:

• The app.module.ts file contains the root module and imports all other modules.
• The common directory contains shared modules, filters, interceptors, middlewares, and pipes that can be used by any module.
• The modules directory contains subdirectories for each module of the application. Each module has its own controllers, services, repositories, entities, interfaces, and other modules that it needs. Each module also has its own set of tests.
• The utils directory contains utility classes or functions used across the application.

Using this structure, you can organize your code in a logical way, making it easier to manage as your application grows. Additionally, you can leverage NestJS's built-in features like dependency injection and module imports to make your application more modular and extensible.
